Victron Orion-Tr DC-DC Converter Isolated 12/12-18A (220W)

The Victron Orion-Tr is a professional-grade DC-DC converter designed for marine electrical systems requiring clean, regulated voltage conversion between DC circuits.

This model has 12V input, 12V output, and a max current rating of 18A.  Isolated.

The galvanic isolation between input and output makes it the correct choice regardless of your system's grounding topology — and the only viable option when the input and output circuits do not share a common negative ground. It is equally well-suited for powering sensitive electronics from a main DC bus where noise elimination and circuit protection are priorities.

A remote on/off terminal eliminates the need for a heavy-duty switch in the main input wiring, allowing control via a simple low-current switch or direct connection to an engine run/stop signal — particularly useful in marine and vehicle installations. All models are fully short-circuit proof, and built-in high-temperature protection automatically reduces output current to protect the unit if ambient temperatures rise. IP43 protection guards against dust and splashing water when installed with terminals oriented downward.

Note: The Orion-Tr is a DC-DC converter. For dedicated battery-to-battery charging with Bluetooth monitoring and charge algorithm control, please see the Victron Orion-Tr Smart.
